Police say three prisoners have broken out of a Quebec City jail.
The three being sought are: Yves Denis, 25; Denis Lefebvre, 53; and Serge Pomerleau, 55.
The men are alleged to have broken out of the Orsainville detention centre.
Police are saying a helicopter may have been used in the escape, which took place Saturday evening.
The public is urged to call 911 if they believe they have spotted any of the men but not to approach them.
